using srand

See Summer snow on the winter of Rand () and srand () produce random number of summary, very good, study, and then have Baidu other people's results, the system summarizes. This article turns from Summer snow winter:

Http://hi.baidu.com/jkxtu1984/blog/item/d5d1f1c6e5ac461d9d163dec.html The standard library (included in ) provides two functions to help generate pseudo-random numbers: Function 1: int rand (void );Returns a random integer between [seed, rand_max (0

Rand ()Returns a random value ranging from 0 to RAND_MAX. Before calling this function to generate a random number, you must use srand () to set the random number seed. If no random number seed is set, rand () will automatically set the random

Srand () is to provide seed for rand (). If srand inputs the same value each time, the random number generated each time is the same, Srand (N) For (10) Rand ()That is to say, using a fixed value as the seed is a disadvantage. The common practice is

use of the Random function rand () and Srand () in C + +First, Rand ()Name of function: RandFunction: Random number generatorUsage: int rand (void);Header file: stdlib.hFunction Description:The internal implementation of RAND () is made with linear

Http://www.cnblogs.com/lenient/articles/1565376.html First we have a general view of Rand&srand: Srand initializes random seeds, Rand produces random numbers, which are described in detail below. RAND (generating random numbers) Table header file:

Summary of the method for generating random numbers using rand () and srand ()   The standard library (included in ) provides two functions to help generate pseudo-random numbers: Function 1: int rand (void );Returns a random integer between [seed,

I. Basics We know that the rand () function can be used to generate random numbers, but this is not a real random number, it is a pseudo random number, it is based on a number, we can call it a kind, A coefficient calculated based on a recursive

The standard library (included in ) provides two functions to help generate pseudo-random numbers: Function 1: int rand (void );Returns a random integer between [seed, RAND_MAX (0x7fff) starting from the seed specified in srand (seed. Function 2:

Summary of methods for generating pseudo-random numbers using rand () and srand () --------------------------------- The standard library (included in ) provides two functions to help generate pseudo-random numbers:   Function 1: int rand (void );
